Since is arithmetic, it's given recursively by
where is a fixed number and is the starting term in the sequence. We have
and so on, so that
We're told that , so
and
so that
Then the first term in the sequence is :
and the sequence has general formula
The first negative term occurs for
The first negative term in the sequence is .
Answer:
Step-by-step explanation:
